  2. Prime editing - Wikipedia

    en.wikipedia.org/wiki/Prime_editing

    CRISPR/Cas9 edits rely on non-homologous end joining (NHEJ) or homology-directed repair (HDR) to fix DNA breaks, while the prime editing system employs DNA mismatch repair. This is an important feature of this technology given that DNA repair mechanisms such as NHEJ and HDR, generate unwanted, random insertions or deletions (INDELs).

  3. Cas9 - Wikipedia

    en.wikipedia.org/wiki/Cas9

    The CRISPR-CAS9 system has the ability to either upregulate or downregulate genes. The dCas9 proteins are a component of the CRISPR-CAS9 system and these proteins can repress certain areas of a plant gene. This happens when dCAS9 binds to repressor domains, and in the case of the plants, deactivation of a regulatory gene such as AtCSTF64, does ...

    en.wikipedia.org/wiki/CRISPR-Display

    CRISPR-Display (CRISP-Disp) is a modification of the CRISPR/Cas9 (Clustered regularly interspaced short palindromic repeats) system for genome editing. The CRISPR/Cas9 system uses a short guide RNA (sgRNA) sequence to direct a Streptococcus pyogenes Cas9 nuclease, acting as a programmable DNA binding protein, to cleave DNA at a site of interest.

  6. CRISPR - Wikipedia

    en.wikipedia.org/wiki/CRISPR

    Cas9 (or "CRISPR-associated protein 9") is an enzyme that uses CRISPR sequences as a guide to recognize and open up specific strands of DNA that are complementary to the CRISPR sequence. Cas9 enzymes together with CRISPR sequences form the basis of a technology known as CRISPR-Cas9 that can be used to edit genes within living organisms.

  7. CRISPR gene editing - Wikipedia

    en.wikipedia.org/wiki/CRISPR_gene_editing

    CRISPR-Cas9 genome editing techniques have many potential applications. The use of the CRISPR-Cas9-gRNA complex for genome editing [10] was the AAAS's choice for Breakthrough of the Year in 2015. [11] Many bioethical concerns have been raised about the prospect of using CRISPR for germline editing, especially in human embryos. [12]

  8. CRISPR activation - Wikipedia

    en.wikipedia.org/wiki/CRISPR_activation

    See: Guide RNA, CRISPR. Complementary base pairing between the sgRNA and genomic DNA allows targeting of Cas9 or dCas9. A small guide RNA (sgRNA), or gRNA is an RNA with around 20 nucleotides used to direct Cas9 or dCas9 to their targets. gRNAs contain two major regions of importance for CRISPR systems: the scaffold and spacer regions.

  9. Gene drive - Wikipedia

    en.wikipedia.org/wiki/Gene_drive

    An RNA-guided endonuclease (e.g., Cas9 or Cas12a [13]) and its guide RNA, which can be easily altered to set the target. [5] Cas9 is the most promising technology identified in a 2014 review. [5] Cas9 gene drives have been successfully tested in 2015, [14] and Cas12a in 2023. [15]
